#82 FINAL LAYER: the peer body-channel trn-lock -- a circling limper skated because the peer's turn-arm had no walk-demand yield and the trn speed exit read a dead replicant mapper cell

The master limped clean (218x gimp-cycle records, zero trn) -- a _ReturnAddress
trap on SetAnimationState(4) proved ALL peer trn arming came from the port's own
mech4 turn-step block, not the type-3 reader.  Two dead ends, one root:
- mech4 peer arm: gated on !wantsWalk (standSpeed < bodyTargetSpeed), exits trn
  when walking demand appears -- the leg twin's authentic precedence
  (part_012.c:12013, the Standing speed test outranks the turn test).
- mech2 body case 4: bspd reads bodyTargetSpeed on ReplicantInstance; the local
  mapper's speedDemand is a dead cell on a peer (reads 0 forever -> no exit).
Verified 2-node timeline: arena circle replicant 218x state-24 / 0x state-4
(was 116x trn churn), grass circle 235-clean, knockdowns bounded, 0 deaths.
Diagnostics kept: BT_TRNTRAP ra-trap, BT_ANIMIND_CAP, [gimpfeed], [replgimp]
extension.  KB: locomotion.md trn-lock entry + the dead-mapper-cell lesson.

+**The LAST #82 layer: the peer body-channel TRN-LOCK (root-caused + fixed 2026-07-30) [T2].**
+After the storm fix, a CIRCLING limper still skated on peers (user repro): post-knockdown recovery
+lands the peer at body-stand; the port's peer turn-step arming block (mech4.cpp `PerformAndWatch`,
+needed because the peer no longer runs the leg channel that cross-arms trn) saw
+`replMppr->turnDemand` (circling → always turning) and armed body state 4 — and NOTHING could exit:
+(a) body case 4's speed exit read the LOCAL mapper's `speedDemand`, a **dead cell on a replicant**
+(nothing writes it → 0 forever); (b) turning never stops for a circler. Peer pinned in trn
+(advance-only churn = leg-lifty skating) while `bodyTargetSpeed` held the replicated demand
+(~24 u/s full). Measured via `[replgimp]` (`bts=24.6 standSpeed=6.83 bodyState=4` in 168/171
+samples) and a `_ReturnAddress` trap on `SetAnimationState(4)` (`[trntrap]`, BT_TRNTRAP → linker
+map: ALL 60 hits from PerformAndWatch = the port's own arm, NOT the type-3 reader — the master
+broadcasts clean gimp states). Fix pair, mirroring the leg twin's authentic precedence
+(part_012.c:12013 — the Standing speed test outranks the turn test): (1) mech4 peer arm gated on
+`!wantsWalk` (`standSpeed < bodyTargetSpeed || bts < 0`), exit trn when wantsWalk; (2) mech2 body
+case 4 `bspd` reads `bodyTargetSpeed` on ReplicantInstance (the replicated demand — the same
+number the peer Standing case walks on). Verified: arena circle replicant 218×state-24/0×state-4
+(was 116×trn churn), grass circle 235-clean, knockdowns bounded, 0 deaths. **Lesson: on a
+replicant, every `MechControlsMapper` demand cell except those explicitly re-derived
+(`turnDemand`) is DEAD — any peer-side state machine judging a local mapper read is judging 0.**
